I wish I had a Ringmaster. I've built 3 S-1's and 1 Baby Ringmaster. But I'm down to none right now. I've got a set of fullsize plans, but I don't think I could knock one out in the remaining time. For me the first Ringmaster (I had an Enya .35 on it) 1968 was the first Controline plane that really felt like something on the lines. That first flight was remarkable and I remember how hard the "pull" on the lines felt. Up to that point I was flying 1/2 A Cox .049's Goldberg profiles. Great learning machines, but the Ringmaster was the real eye opener. Today I ran across the original assembly sheet Sterling provided. It makes for an interesting read and remembrance of my Ringmaster builds. Everybody who flies controline should have a Ringmaster sometime. Sometime I'll have another.
